The general description of the machine thus far given constitutes no part of my invention, it being merely described to enable those skilled in a the art to understand the general construction z igigg g zgg f of Whlch I have shown of the machine to which my invention relates. e A Movement is imparted to the heel holder clamping Flgure 1 IS Such portlons device, and a foot 15 bears on the curved track 45 of Wood h ee1 tummg machme as I E 16.

I support 18. A block 19 is secured to the side 1 5 Figure 2 1s a bottom plan view of a preferred of th rved track 16. yp of the Wedge- As one mounting for a track, I have shown in Fi ure 3 is a i e eleva i n o an n a d Figures 1 and 3,abo1t 20, having a threaded nut al of a d ta of th wedge m unt n f the. 21 thereon. The clamping bolt extends up holder guide. through an opening in the wedge 25 and an open- 1 0 ing 22 in the block 19, and a head 23 is secured on top of the bolt 20 to permit vertical movement of the block 19. p

A wedge block 25 having a cut-out slot 26 therein, and with serrations 27 preferably on its lower face, is mounted between the block 19 and the arm 18. An adjustable screw 28 having a calibrated head 29 is journaled in the arm 18, and can be elevated to a desired position to seat within one of the narrow teeth 27 of the lower surface of the wedge member. The side of the wedge 25 may be calibrated, and when the nut 21 is released, the wedge member may be moved readily to a desired position.

The wedge 25 has its lower side arching around the upper side of the support member 18. This is best seen in Figs. 4 and 6, where the wedgev 25 has been adjusted back from its position in Fig. 3. This is because the notched portion of this lower side of the wedge and the forward unnotched portion of the wedge are not in a straight line but divergent at a wide angle. If these portions were in a straight line, adjustment of this wedge 25 merely would vary the elevation of the guide and not its inclination. The wedge 25 thus has a combined rocking and elevating or lowering action when adjusted, so that it is efiective for moving said guide in a series of non concentric arcs.

In the modification illustrated in Figure 4, there is the same support 17 having a lateral arm 18. I have shown a bolt 20a extending through the arm 18 and passing through the groove of the wedge member 25, which is similar to the wedge member illustrated in Figures 2 and 3. The guide track 16 has a block 19a secured to its outer side, and the bolt 20a passes through a tapered aperture 30 and has a head 31. An auxiliary wedge 32 having a slot 33 through which the bolt passes, is illustrated in this modification, which, as will be obvious, permits the guiding track to be clamped down at a predetermined inclination. In Figure 6 I have shown the upright arm 17 mounted on the machine frame, and the side arm 18 extends out from the upright 17 in a manner similar to the mounting shown in the other figures. The track 16 is held in position by means of a wedge member 25 in the same manner as in the other modifications. In Figure 6, instead of providing an adjustable screw, the end of which seats Within the serrations within the lower surface of the wedge, I have merely provided a ridge or elongated tooth 33.

In Figure 6 I have indicated in dotted lines the position which the track will assume upon the advancement of the wedge to increase the angle of inclination of the track. In order to increase the inclination of the track, the wing nut 21a, must first be backed off and the wedge 25 can then be pushed, as indicated, to the right or left.

It will be obvious that with the wedge mounting which I have provided, more accurate con trol of the angle of inclination of the track and a greater range of adjustments to various angles of inclination may be provided and recorded. With the wedges provided with calibrations as indicated, an operator can readily set up the machine for a given heel, be instructed as to how far in to insert the wedge, and the contour which will be given to the heel can thus be very accurately controlled. The calibrations being extended along the side of the wedge member, can be much farther apart and thus more readily visible when an auxiliary calibrated screw is used.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:-
